In June 2010 the overhead dvd player quit working and the bose in-dash stereo systems began to intermittently work and not work. In May 2012 the windshield wipers would sometimes not turn on and at times in operation would stop operating mid way. At the same time, the bright lights sometimes would not come on. Moving the steering column up and down would allow the brights to operate, but in most cases they don't work at all. The heat & A/C fan motor only works on high speed as well leaving the other speeds inoperative. It seems there may be an electrical issue in the steering column and I'm not sure if the stereo and dvd player would be somehow connected with that portion of the wiring harness. I contacted Chevrolet and they say there are no open recalls for our VIN number.

I have had multiple issues with my 2002 Chevy Trailblazer where the 4X4 selector switch will not work, or while driving at highway speeds the vehicle will be put into four wheel drive while the selector switch is still turned on two wheel drive. The selector switch at times has not worked when I wanted to make the vehicle go into four wheel drive. I have found out the vehicle is in four wheel drive by having a hard time turning the front wheels and seeing the front tires spin on loose gravel even though I never switched the vehicle into four wheel drive and the selector switch states it's still in two wheel drive but the yellow light is lit up that it's in four wheel drive. I have complained multiple times to GM and have had the selector switch replaced 3 times but it still continues to happen. Everytime that GM looks at it they say that it is working just fine. I have seen and heard that many other people are having the same problems with this. I feel there should be a safety recall put out for this drive selector switch.

I feel that even if you have had a recall issue once and the situation continues to happen then it needs to be fixed until the problem is solved I have contact GM several time and nothing has been done to ratify my problem with the windshield wipers and the 4 wheel drive and several other recall issues this is sad I say we need a class action law suit I am not one to take legal action but for people that have this kind of money and to not fix their problem that they put out on the roads for us to drive safely is shameful.

My 2002 Trailblazer 4X4 came locked up completely with no possibility to even open door with the key. Chevy dealer blamed the module vcm located under the behind seat that must be changed. Re-programming all seems working but erratically until the effective change of vcm module. Is there a possibility to repair it ? thanks [xxx] information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

The rear right and left brake lights and rear turn signal lights have burned out repeated. I purchased the 2002 Chevrolet Trailblazer in December 2001. The problem first started to occur when the brake lights failed at 30,000 miles in 2003. I had to replace the circuit boards the lights plug into at my own cost to fix the problem. There was a recall to replace the circuit boards in 2004, NHTSA #04V527000, which I had performed on the vehicle. Subsequently the circuit boards burned out again a few years later. I took the vehicle back to the dealership and they said they wouldn't replace the circuit boards at their expense. I then purchased and installed the circuit boards myself. In 2010 the circuit boards burned out again. I took the vehicle back to the dealership and they investigated and said they couldn't find anything wrong with the vehicle other than the circuit board. They charged me $191.50 to investigate the problem and change out the circuit boards again. This is a safety issue because the rear brake lights and rear turn signal lights not working increases the risk of a crash. I received a ticket/warning on 2-2-11 for the brake lights not working but expect the brake lights will become inoperative again soon as this is the 5th set of circuit boards that have been placed in the vehicle and they keep burning out, and Chevrolet/General Motors hasn't supplied a satisfactory correction to solve the problem. Current mileage is 159,000 and the problem started at 30,000.

Chevy 2002 TB lt/4WD - multiple electrical problems since purchased (used 3/2010). Started with rear ww non-function which Chevy dealer charged $1500 to repair, claiming it was bad body wiring harness and it was not an uncommon problem but Chevy would not take any responsibility. After repair, other electrical issues have popped up from things as simple as outdoor temperature gauge not working, passenger window won't roll up/down (though motor is fine) as well as pass electric doorlock and mirror nonfunctioning. Larger occurring issues which could effect safety include the vehicle randomly deciding to change from 2wd/A4wd/4wdh4wdl whenever it wants to under various weather/road conditions (including perfect weather and road surface) and occasional random ignition system failure. Otherwise great vehicle with seemingly normal wear and tear problems but Chevrolet's refusal to acknowledge responsibility and provide repair is disgraceful, irresponsible and dangerous.

My headlights started to flicker one seasonably winter day. I had the heater motor replaced 2 months prior to this incident and back wiper motor just a month before this.then the heater motor cut out, and did so numerous times as I traveled on a 20 degree day. It seemed to run fine after that for the most part that day. I later got into it and again headlights flickered and heater motor cut out. Especially when I would accelerate or turn to the right. I replaced the battery, alternator and had ground wires cleaned only to have it recur a week later. I do most of my driving at night and when the lights went out and came back on I had enough. This had become quite costly and my mechanic was at a loss as to what to do next. I took it to a Chevy dealer and traded it in on another vehicle, as I can no longer afford to keep spending money on a mystery issue.

First the left side of my temperature control lighting went out, a week later I got a steady service engine soon light, it then went out after a few minutes, it then stayed steady for a period of 2 days, then went out. Then 3 days later my indicator light above my 4-wheel drive control went out, I attempted to change the fuse, then got a service four-wheel drive warning.

Car running great, parked it for an hour then got in my car and it wouldn't start. Dash lights and radio came on but wouldn't turn over. Took the key out, front headlight stuck on. Kept trying to start. Opened hood, smoke coming from fuse box. Removed fuse box cover, the fuse box was melted over the fuses and was on fire. Disconnected the battery and put out the fire.

Details: I have a 2002 Chevy Trailblazer. When I press on the accelerator the vehicle will lose power for a moment and regain power in heavy traffic. Also, the service engine light will come on. I took this vehicle to a service center and they told me the repairs that it supposedly needed. Everything from the fuel pump to every sensor that you can think of. Now it seems to be something with the electrical system. I have already replaced the whole steering collum and everything that they suggested. But the problem with the vehicle did not change. This vehicle has been doing this for 8 months with. I believe that there is a electrical issue somewhere in my vehicle. Somebody help!

- Albuquerque, NM, USA

I have a 2002 Chevy Trailblazer. My inside lights have stopped working and I assumed that is was due to a blown fuse. I took it to the Chevy dealer ship and they stated that I may have a wiring problem. The wire the connects to my headlight burns out easily and my bulbs for my taillight has to be replaced often. Can you please assist. I have to replace the head light wiring several time and have to replace the tail light bulbs. The problem started several years ago. The last time that I had to replace a part was December of 2009.

It has the "memory" mirror option which includes featuring memory set options for driver 1 and driver 2, as well as rearview curb assistance (the mirrors will tilt down to your setting to help parallel park when in reverse).the mirrors quit holding their memory, causing me once again to have to reset the mirrors every time I got in the car. On numerous occasions, I thought my mirrors were reset, and then I would look to change lanes and find my mirror tilted up towards the sky or some erratic place. Not to mention the safety issue, but it has been an extreme annoyance. Went to the dealer multiple times and they "reset" the mirrors, but they don't know the cause.

I own a 2002 Chevy Trailblazer and I have had my headlights checked because not always but once in a while they just completely turn off sometimes at night time while driving. I took it in to a repair shop and nothing was found wrong with it but the problem continues I have to have headlights and brake lights changed like every month or so my truck one day didn't turn on couldn't figure out what was wrong with it sat in my garage for about 3 days and everyday I would try to turn it on but nothing after the 3rd day went and tried again it came on without a problem and it's been okay just the problem with my headlights still going off at night once in a while. I know 2 other people who have 2002 Chevy Trailblazers and have had kind of the same problems. I believe that their is an electrical problem with the 2002 Chevy Trailblazers.

Purchased new 2002 Trailblazer ltz which has had this problem since 2005. Driver & passenger mirrors position themselves erratically at every ignition and sometimes while driving. A constant twitching on the passenger side also occurs while driving. It is very dangerous when mirrors are not positioned correctly once driving. Chevrolet dealer failed to find the fault and reprogrammed twice. No parts have been replaced as they have now idea what the problem is or how to fix it. This seems to be a common problem, however.

- Templeton, CA, USA

The contact owns a 2002 Chevrolet Trailblazer. The contact stated that the brake lights in his vehicle were completely inoperative. The dealer replaced the brake lights, but the failure recurred. In 2005, the instrument panel made a clicking sound and sporadically failed. The contact believed that the failure was directly related to the brake lights. The dealer stated that the instrument panel failed and the contact paid to have it corrected. In 2008, the instrument panel failed again and completely stopped working in January of 2009. He spoke with two different mechanics and they stated that there was a recall for the failure. The manufacturer stated that the vehicle had been previously repaired according to NHTSA campaign id number 03V096000 (electrical system:wiring:interior/under dash); therefore, they could not assist. The current mileage was approximately 170,000 and failure mileage was approximately 113,000.

The electronic sensors and key fob to open and lock the vehicle do not work, causing serious problems because the rear tailgate door will not unlock manually and all of the emergency equipment is stored under the carpet in the tail section. This problem started in cold weather and even replacing the batteries in the key fob didn't work. This is serious in cold weather for emergencies ie, cables to jump the car and flares are stored in the back of vehicle.
